vVhen handling money it is frequently necessary not only to add and list different items, but also to break up or analyze the items into the diderent monetary denominations required for the payment thereof, and to add these separate denominations for the different items listed.

This is especially true when making up payrolls, or otherwise disbursing the monetary items listed, since for this purpose it is necessary to know in what denominations to draw the money from the bank, as well as the total amount of money to be withdrawn. A large amount of tedious and time consuming work is required to do this by mental calculations, and under such conditions frequent errors are unavoidable and these errors are very annoying when they happen.

The adding and listing can be readily accomplished upon any of the conventional adding and listing machines which are now in very extensive use, and I am aware that denominating machines have also been produced and used to a certain extent prior to the present invention, although these denominating machines are such complicated and expensive mechanisms as to be impract' al for use except by large concerns havr, such a heavy payroll that the puchase of expensive special equipmentl for handling the same is justiiied. However, practically every individual or concern conducting a business involving the handling of even small amounts of money has one or more adding machines in its equipment, and the object of the present invention has been to provide an attachment which can be readily applied to a conventional adding machine and which, without interfering in any manner with the usual operation of the said machine will enable tlie machine to be used for the additional purpose oit denominating.

Among the further objects of the invention is to provide a denominator attachment which can be easily and quickly placed in position upon an adding machine or removed therefrom without any appreciable delays or loss of time, which is comparatively simple in construction so that it can be produced and marketed at a moderate cost, and which will operate with the necessary accuracy and precision to analyze different monetary items into the respective denominations necessary for the payment thereof, and record these denominations so that after a number of items, such as the items of a payroll have been added and listed the operator will know not only the total amount of the payroll7 but also the denominations in which it must be withdrawn from the bank in order that the different amounts can be placed in the respective pay enevelopes or otherwise disbursed.

The above and other features of the invention will be readily understood from the following specification together with the accomrianying drawings, in which Figure l is a front elevation of a denominator attachment constructed in accordance with the invention, showing the same in operative position upon an adding machine, all those portions of the adding machine which are not essential to the illustration of the present invention being broken away;

Corresponding and like` parts are referred to in the following description and indicated on all of the views of the drawings by like reference characters.

r1ihe denominator attachment may be designed and constructed in such a manner as to be readily applied to any of the well known adding and listing machines which are in use. Such an adding machine has been illustrated on tie drawings in a fragmentarymanner, being designated in general by the reference character A. The keys 1 of the adding machine are of the usual construction and are arranged according to the Vdecimal system. rShe usual special keys. 2,

such as the column correction, or the error key, repeat key, andthe like are shown as arranged at the rear ofthe several' banks of decimally arranged keys 1. After the mechanism of the adding and' listing machine has been set in the usual manner by depressing the proper keys 1, the machine is caused to function by pulling forward upon the main actuator or operating handle 8 at the right hand side thereof. T his adding and listingmachine may be-of any conventional and well known construction and it is not thought necessary to describe the same in further detail, since no claim to noveltv is placed thereon.

rlhel denominator attachment comprises a light frame or casing4 which is adapted to be superposed upon the adding machine A., and which is provided with keys 5 corresponding to the decimally arranged banks et keys 1. rlChese keys 4 are provided with stems 6 which extend through the casing 4, being slidably mountedtherein, and termi nate at their lower ends in spring clips 'Z' of a suitable character to engage the adding machine keys 1. Any suitable means might be provided for connecting the stems 6 of the attachments to the adding machine keys, although a construction such as the spring clips has the advantage of enabling the attachment to be quickly placed in position or removed therefrom without any delays or loss of time. Spring clips, such as those illustrated may be constructed to have a resilient action so that they will automatically grip the respective adding machine keys when the attachment is placed in position and become disengaged therefrom when the attachment is released and forcibly removed. @wing to the fact that the keys 5 of the attachment become interlocked with the adding machine keys when the attachi Lent is in use, the necessity of providing separate springs and locking means for the keys of the attachment is avoided. 1n other words, the keys 1 of the attachment remain depressed, after being operated, as long ,as the corresponding keys of the adding machine remain depressed, and are returned to their original position after the adding machine has been operated and the adding machine keys returned to their original position.

'if he casing 4 of the attachment is adapted to be supported over the top of the adding macl'iine A in a spaced relation thereto, and special means is provided for holding the casing rigidly inoperative position and at the same time permitting of quickly applying the attachment to the adding machine or removing it therefrom. For this purpose the forward end of the casing 4 is provided with depending feet 8 and said feet carry downwardly projecting headed studs 9 which are adapted to interlock with lateral notches 9d in the end of a transverse bar 10 which is permanently secured to the forward end of the adding machine. This bar 10 is secured to the adding machineby fastening members such as the screws 11 andis held in a spaced relation thereto by means of suitable collars or washers 12 which may be of rubber or resilient material desired. A similar transverse bar 13, shown in detail by Figure 14, is secured to the back of the adding ma.- chine. rlhe notches 14 in the ends of this bar are engaged by headed studs 15 carried by the depending feet 16 at the rear of the casing 4 (see Figures 4 and 11). The transverse bar 13 is alsofprovided with a stud 17 which is adapted to be engaged by a hook or detent 18 for the purpose of positively locking the attachment in position so that there will be no possibility of the attachment being shifted out of proper engagement with the adding machine keys by the vibration and ars which are incident to the vibration of the adding machine. rlhe locking hook 18 is shown for convenience as carded by a cross bar itl-which connects the rear feet 16 of the attachment.

lVith this construction it will be obvious that the attachment is handled as a unit and that it can be very quickly placed upon and loci-:ed in operative position on the adding machine, or iicnioi'ed therefrom, no tools ot any kind being required 'for tl purpose.

Slide-.bly mounted within the casing flis a series oi register actuating slides which are operatively associated with the keys so that when keys corresponding to any monetary value within the capacity oi' the machine are depressed, the slides fill be set to analyze the amount into dilierent smaller denominations of which it is composed, and to register these denominations upon the actuation oi' the adding machine. The registers 20 are shown for convenience as arranged at the forward end oi the easing and a separate register is provided for each monetary denomination. These registers are adapted to be read through suitably arranged sight openings 2l in a plate 22 which extends across that end oi the casing in which the registers are mounted. For convenience the registers are shown as arranged in two transverse rows and carried by the transverse shafts 23, the ends ot the shafts projecting from the casing and being provided with knobs Q-i which can be manipulated to reset the registers and bring them back to Zero position. The various registers are actuated by means of pinions Q5 which engage racks 2G upon corresponding register actuating slides. The actuation ot each register thus depends upon the extent of movement of the corresponding slide, and certain of the slides are arranged to have diiierent increments of movement so that one or more coins or bills may be registered as is necessary.

The various register actuating slides are shown in detail by Figures 3, 7 and 8, and the arrangement thereof with respect to the banks ot keys is shown by Figures 2 and 5. Each of these slides is connected to a tension spring 27 which is normally maintained under tension and tends to draw the slide forward to actuate the corresponding register vlien the slide is released. The springs 27 tor all but two oit' the slides are arranged within jthe casing and attached to a transverse partition therein. The springs 27 for the other two slides arel arranged under the casing, as indicated by Figure 3, and suitably attached to projections on the bottom of the casing. The rear ends of the slides are provided with shoulders 29 and depending arms or hook members 30. The shoulders 29 of the slides -itor each bank of keys are engaged by the nose ot a detent- 31, said detents being shown as carried by hubs 3l which are loosely mounted upon a transverse shaft 32 at the rear end oit the casing. The register operating slides are thus normally held in a rearwardly retracted position against the action ot the respective springs 27 by means ot the detents 31.

`When a key in any bank or keys is depressed the detent 3l tor the register operating slides of that bank or' keys is automatically moved into inoperative position. For this purpose a detent releasingl slide is provided if r each l sank et keys, the rear end ot each the said slides haring a pin and slot connection 34s with the corresponding detent Si, and the slides being provided with Literally projecting pins or shoulders arranged to be engaged by cani portions 36 on the stems oit the keys for the attachment. Springs 3T are connected to the detent release slides 3:3 and normally ,na to more the same -forwardly into operative position. The pins 35 of the slides are then in engagement with the key ste if' i and arranged under the cams 3G. lh-en any one ot the keys is depressed the cam 3G thereof engages the correspon ding pin S5 and cooperates therewith to move the detent releasing` slide ior that bank ot' keys rearwardly gains-t the action oit the spring 37, with the result that the corresponding detent Qn is swrrg upwardly and the group oi: re. actuating slides 'for that particular b s is released.

n s or hook members oi the actuating slides are normally eng; ed by the cross bar oii a bail 23S which is rigid with the betere-mentioned shaft 3Q, the cross bar of the bail operating within suitably arranger segmental slots 39. A crank arm el() which is rigidly applied to a projecting end oi: the shaft SQlhas a pin and slot connection il with a link member 4:2 which is operatively connected to the lever or handle 3 ot the adding machine A. For this purpose a bracket or clamp 4:3 is shown as applied to the operating lever 3 oi' the adding machine, said clamp being provided with a stud 44 which is detachably engaged by a hook 42 at the end of the link member 42. The bracket i8 is shown as formed of two con'iplemental parts which can be applied to the operating lever 3 oi' the adding machine from opposite sides thereot and permanently clamped in position thereon by the screws 45. However, the hooked end of the link has a detachable engagement with the stud 44: so that these parts can be quickly connected or disconnected when placing the attachment in position u on the adding machine or removingit ther Agoin. 1When the operating lever 3 is swung forwardly to actuate the adding m chine A in the customary manner, the motion thereoil is transmitted through the link 4Q and crank arm 40 to the shaft 32, with the result that the said shaft and the bail 3S carried thereby are rocked. The arrangement is sneh that the bail 38 is swung forwardly, and any oi the register operating slides which have been released by the detents 31 can then ymove forwardly under the action of the tension springs 27. Suitable stops are provided and controlled by the keys for governing the extent ot movement of each of the slides, so that the corresponding registers will be properly operated. Upon the return movement ot the main operating lever 3 the bail 38 is swung rearwardly and engages the hooks or arms 30 et ot the register operating' slides that have been moved forwardly, with the result that all such register operating slides are returned to their original positions. Upon the completion of the adding and listing operation, the keys l of the adding machine are released and returned to their original positions, in a manner which is well known, and the keys of the attachment will be returned -to their original positions at the same time., with the result that the detente 3l will be in position 'to eng ge the sho lers 29 of the register operating slides which are reset or returned to their original positions by the action oit the links 42. The pin and slot connection between the upper end of the link 42 and the crank arm 40 provides tor a limited amount ot play between the parts and enables the main operating lever 3 ot' the adding machine to have the necessary greater amplitude of movement than the bail 38.

rlhel unit bank ot keys is provided with register operating slides a and Z), one of which is arranged upon each side ot the stems for the keys (see Figures 2 and rlhe tens bank of keys is provided with :tour register operating slides d, e, f, and g, two ot which are arranged on each side of the key stems. A dierential nickel vbar o is arranged between the unit bank ot keys and the tens bank of keys, being operatively connected, Ias will be hereinafter described, to the slides and (Z. The hundreds bank of keys is similarly provided with slides a and 714, the thousands bank of keys vwith the slides j and c, and the ten thousands bank of keys with a slide a. rlhe three said slidesa are identical in construction, and the slide a for the pennies or units bank or column is shown by Figure 3. The upper edge of the slide a is provided with a series of stops al, a2, a3, a4, a5, a6, al, as and a9, which are adapted to engage cooperating stop pins 46 on the stems of the respective keys tor the purpose of properly governing the amplitude of movement `ot the slide when it is released. rlhis is the pennies slide and the rack 26 thereof operates the register 20 for cents or pennies. The before-mentioned stop shoulders on the slide are arranged with respect to the pins 46 ot the keys so that the slide will have ditferent increments of movement after being released, depending upon the key which has beenfdepressed. For instance, the stop shoulder al will permit Vthe slide a to have one increment of movement before engaging the pin 46 of the one cent key in the cents or lunits column or bank of keys. If the two cent key is depressed, the stop a2 is so arranged that the slide will have two increments of movement before it engages the pin 46 of the depressed key. Similarly, the stop a3 will permit three increments of movement when the three cent key is ydepressed and the stop at will permit tour increments ot' movement when the four cent key is depressed. The penny or cents register 2O will thus register one, two, three or tour pennies, depending upon the value of the key which is depressed. `When the live cents key is depressed, there will be a five cent piece or nickel registered instead ot tive pennies and no movement of the cents slide a is desired. Accordingly, the stop shoulder a5 thereof is so arranged that it is engaged by the stop pin 460i the five cents key as soon as the said key is depressed. rlhe registration of the nickel instead of live ypennies is taken care of by the slide b, in a manner which will be 'hereinafter described. rlhe stop shoulders a6, al, as and a9 have the same relation Ato the pins 46 of the corresponding keys as the shoulders 0,1, a2, a3, and 0:4 have to the one, two, three and four cents keys. This is due to the tact that the same number of pennies are involved and should be register-ed. Ot cour e, for the siX,seven, eight and nine cents keys a nickel or ve cent piece will be registered in addition to the pennies.

rhere are lthree nickel slides .or bars, said bars being illustrated in detail by Figure 8. The bar or slide Z) is associated with the units column of keys and the bar or slide Z is associated withthe tens column of keys, the bar c being .rranged at an intermediate position and elevated slightly above the other bars, as is illustrated more clearly by Figure 5. rlhe intermediate nickel bar o is termed a differential -bar and the forward end thereof is provided with the rack 9.6 which vengages the pinion 25 ot the nickel or live `cents register A2O. Neither ot the nickel bars or slides b or d is provided with `a .rack or has any direct connection with .the vregister 20, although the three nickel Abars or slides are operatively connected in such a. manner that it either ofthe slides Z) or CZ is permitted to move Jforwardly one step or increment, the differential bar or slide c will cause a single nickel or ivecent piece to be registered while it bothot the 'bars 'o and (Z `move forwardly onestep or increment at the har Z) of the units column thus engages the lower end of the lever 47 while the pin 48 of the nickel bar (Z for the tens column engages the upper end of the lever 47. It will thus he obvious that it either one ot the nickel slides Z) or (Z is permitted to move forwardly one step, the nickel differential slide c will receive a single increment of movement, while it both ot the nickel hars or slides Z) and (Z are permitted to move torwardly at the same time the nickel. ditlierential har o will receive two increments ot' movement. The nickel har is provided with the stops b1, b2, b3, b4, b5, 6, Zf, Zig and Zr which correspond to the keys ot' the units column. VEhe stops Z1 to Z)d are arranged to he engaged hy the stop pins 46 ot the keys as soon as the keys are depressed, so that when any one ot' the corresponding keys is operated there will he no actuation ot the nickel register. The stop shoulders b5 to Z2 inclusive are arranged so that the har b will he advanced one step forward and cause a single nickel to he registered it any one ot the correspondingl keys is actuated.

T he stop pins 46 of the keys 5 ot' the units column or bank cooperate with the stop shoulders of the two slides or hars (L and o so that for any value from one cent to nine cents the penny and nickel registers 2O will he actuated according to the numher ot pennies and nickels which are necessary to make up the value of the depressed key. For the values of one cent to tour cents the nickel slide b is not actuated although the penny slide o receives different increments of movement corresponding to the value ot the depressed key so that there is a proper actuation ot the penny register 20. Then the tive cents key is depressed the penny slide (L is locked against movement while the nickel slide Z) is permitted to move forward to actuate the nickel register owing to the tact that tie shoulder b5 thereof does not the stop pin 4G ot the key until after the nickel slide has had an increment ot' movement. l.ilhen any one ot' the keys trom si): cents to nine cents is depressed, the nickel har Z is permitted to move forward to register one nickel, while the penny slide a is permitted to move forward different increments. depending upon the number of pennies which may be required in addition to the nickel to make up the value oi the depressed key all as previously described. All of the values from one cent to nine cents are thus taken care of hv the slides (t and Z) of the units column ot keys.

The tens column otI keys, as previously mentioned, is provided with the four register operating slides or hars (Z e, f, and gf, two of which are arranged on each side ot the key stems. The bar (Z, as previously mentioned s ri s to actuate the nickel register, being 'crowded with the shoixlrlers f, el", (la, (Z4,

(Z5, (Z6, (Z7, (Z8 and (Z9. The shoulders (Z1, (Z2, (Z5, (ZG, and (Z7 are arranged to engage and cooperate with the stops ot the corresponding keys to lock the bar (Z against movement when any one of the said keys is depressed, while the stops (Z3, (Z4, (Z8 and (ZD are properly spaced from the vertical paths ot the stops ot the corresponding keys to permit a :forward movement of the nickel bar to register a nickel when one ot' the corresponding keys is depressed.

The har or slide c controls the dime or ten cents register and is provided with the stops el, e2, c3, c4, e5, e, @7, es, and e9. he stops el', c4, e, and e9 are properly spaced from the vertical paths oi' the stops ol the corresponding keys to permit a single increment of forward movement to register a single time when one of the corresponding keys is depressed. The stops e2 and e7 are properly spaced trom the vertical paths of the stops ot the correspondin g k ys to permit two increments ot forward movement when one ot the corresponding keys is depressed, thereby providing for the registration ot two dimes. The stop shoulders e3, e5, and es are arranged to engage the stop pin of the dime har or slide c and lock the same against movement when one ot the corresponding keys is depressed.

The actuating har or slide t'or the quarter or twenty tive cents register 2O is similarly provided with the stop shoulders f1, f2, 7f3, f4, f6, fz fs, and ff. The Stops f1, f2, a and f7 are arranged to engage the stop pins 46 ot the keys and lock the har against movement when one ot' the corresponding keys is depressed, while the stops f3, f4, fs, and ff are each properly spaced from the paths ot the corresponding stop pins 46 to permit a torward movement of the har or slide to register a single quarter or twenty-live cent piece when one of the corresponding keys is depressed. Similarly, the actuating har or slide g for the titty cents or halt dollar register 2O is provided with stops ('1, g2, g3, g4', g, g, 97, g8 and g, ot which the stops g1 to g* are arranged to lock the har or slide against movement when one ot the Correspending` keys is depressed, while the stops g5 to g inclusive are each properly spaced from the vertical paths ot the stop pins of the corresponding keys to permit a forward movement of the har or slide g to register a single halt dollar or iilty cent piece on the titty cents register when one of the corresponding keys is depressed.

The 'tour register actuating hars or slides (Z, e, f, and g are all controlled hy the stop pins 46 ot tens column o't keys 5, and the arrangement is such that when any one of these tens keys is depressed the mechanism is set to analyze the value into the different smaller denominations of which it is comprised and lto register the lproper number of the t' ent. dfwmminatione on the eoV isters Q upon the actuation of theadding machine A. F or instance, when the l key of the tens column is depressed, all of the slides or hars are Vlocked'against movement with the exception of the dime har or slide e, which is permitted to move forward one increment and register one dime on the dime or ten cents register 2O when the adding machine is actuated. lf one of the keys of the units column is depressed in conjunction with the l key of the tens column, the proper number of pennies and nickels to complete the total value of thetwo depressed keys will be registered, the loars or slit es of the units column loeing controlled and actuated as previously described. Should the 2 key of the tens column he depressed, all of the register actuating slides would be locked except the dime slide e, which would loe permitted to have two increments of forward movement to register two dimes upon the actuation of the machine. lf the 3 key of the tens column is depressed, the dimes slide c and fifty cents slide g will both be locked against movement while the twenty-live cents slide f and nickel slide c7 will each he permittedv to have a single increment of forward movement to register one quarter and one nickel on the appropriate registers 20. lf the il key of the tens column is depressed, the fifty cents slide g will be locked against movement while each of the slides c7, c and y will be permitted to have a single increment of forward movement and actuate the corresponding registers 2O to reg- 'ster one quarter, one dime and one nickel. lf the 5 key of the tens column is depresset all of the slides will he locked against movement with the exception of the fifty cents slide g, which will he permitted to have a forward movement to register a single halfdollar or iifty cent piece on the proper register 20. Similarly, the depression of the 6 key of t ie tens column will set the mechanism to register one half dollar and one dime,

the depression of the Y key of the tens column will set the mechanism to register one half dollar and two dimes; the depression of the 8 key of the tens column will set the mechanism to register one titty cent piece, one quarter, and one nickel ;,depression of the 9 key ofthe tens column will set the mechanism to register one fifty cent piece, one quarter, one dim'J and one nickel. i

Vlhen certain keys of the units column are operated in combination with certain keys of the tens column, it is necessary to provide for a double increment of movement for the nickel differential har c so that two nickels will he registered on the tive cents register 20. For instance, if the sum of thirty-live cents is set up on the keyboard, the depression of the 3 key of the tens column will set the mechanism .to provide for the registration of one quarter and one nickel, while the depression of the 5 key of the units column will provide forY the registratioirof a second nickel. Owing to the fact that the nickel slide 72 of the unitscolumn moves forwardly simultaneously with the nickel slide Z of the tens column, a double increment of movement will he imparted to the nickel difierential har slide c with the result that one quarter and two nickels will be registered. ln an analogous manner two nickels are registered when forty-live cents, eighty-live cents, or ninety-live cents is set up on the keyhoard. TWhen twenty-live cents is set up on the keyboard', two dimes and one nickel are registered.

Of the two slides a and 7L provided for the hundreds column, the slide a is identical with the slide a of the units column, since the registration of dollars for the values from one dollar to nine dollars is controlled in an identical manner with that of the registration of cents from one cent to nine cents. The actuating har or slide 7L controls the live dollars register Q0 and is provided with the stop shoulders 7L1, 7L2, 7L3, ht, 7a?, 71.6, 717, 71,5, and 7e?, arranged as shown in detail hy Figure 7. rl`he stops 7L1 to 7# inclusive lock the slide 7L against for .fard movement when one of the corresponding keys is depressed, while the stops 7t5 to /tg inclusive permit one increment of forward movement for the purposeofregistering one live dollars on the live dollars register when one of the corresponding keys is depressed. Thus, for values of one dollar to four dollars,the five dollar har 7L is locked against movement while the dollars har or slide a is permitted to have different increments of forward movement, depending upon the value of the depressed key; when the live dollars key is depressed the dollars slide or har a is locked against movement while the five dollars bar or slide 7s is permitted to move forwardly and register one i'ive dollars. F or values from sin dollars to nine dollars the five dollars har 7i is permitted to move to register one tive dollars, while the dollars har a is permitted to have diiferent increments of movement depending on the number of one dollars which are required in addition to the five dollars tol complete the value of the depressed key.

For the thousands column there is a ten dollars bar or slide j and a. twenty dollar or slide 7c, saidv slides being shown in detail by Figure 7. rllhe har j is provided with the stop Shoulders r, r, e r, r, r, of which the sto 3s jl, j?, and y are each arranged to permit a forward movement of the har to register one ten dollars on the ten dollars register 20, whilethe stops jt, j, and js are each arranged'to lock. the ten dollars bar or slide j against movement. rlhe twenty dollars bar or slide 7c is likewise provided with the stops 701, k2, 7c3, 7st, 7c5, 7c, 757, 70S, and kg. rlhe stop 731 locks the twenty dollars slide 7c against movement when the corresponding' CTI restrictive sense.

Cri

. twenty dollars, and the stops las and ,t each permit four increniients of forward movement to register four twenty dollars. it will thus be obvious that when any one of the keys of the thousands column is depressed, the value of the key will be analyzed into the different twenty dollar and ten dollar denominations and the correct number of the two denominations corresponding to the value of the key registered on the appropriate registers 20.

The ten thousands column of keys is provided with a single slide or bar a which controls the actuation of the one hundred dollars register 20, the arrangement of the stops on this slide being identical with that of the other two slides a of the hundreds and units columns respectively. In the present construction the ten thousands column is only shown as utilizing four keys. It will be understood, however, that I am merely describing one possible embodiment of the invention in detail for illustrative purposes, and that the specication and drawings are to be considered in an illustrative sense and not in a The capacity of the machine can beV readily enlarged or decreased, as may be found necessary or desirable. Furthermore, the arrangement ofthe cooperating stops and the inter-relation of these operating slides or bars of diHerent columns of keys can be varied to denominate in different ways, the essential consideration being that each of the various items which are set up on the adding machine be analyzed into the different monetary values or denominations of which itis composed so that when the operator takes his final result from the machine, he will know all of the different items and the total value of the items, and in addition thereto the difv ferent denominations and the total number of each of the different denominations which must be drawn from the bank or otherwise secured in order that the different items on the list may be placed in pay envelopes or otherwise disbursed.

The complete cycle of operation of the denominator attachment when any item is set up on the keyboard, is as follows :-If the value $297.85 is set up on the keyboard, one key in each column 0r bank of keys will bedel pressed, with the result that all of the detent releasing bars 33 will be moved rearwardly by the action of the cams 36 on the pins 35, and all of the detents 31 swung upwardly away from the shoulders 29 of the register actuating bars or slides. All of the said bars or slides are thus released, although they are initially held against movement by the resetting bar or bail 38. Upon the forward swing of the main operating lever 3 of the adding machine the resetting bar or bail 38 is moved forwardly so that all of the register actuating bars or slides are free to move under the action of the tension springs 27, with the exception of those slides which are locked against movement by the cooperating stops on the slides and stems 6 of the keys. For the particular value of $297.85, which has been taken as an example, the bar or slide a of the ten thousands column will have two forward increments of movement and register two one hundred dollars on the one hundred dollars register 20. The slides or bars j and c of the thousands column will move forwardly, in the manner previously indicated to register four twenty dollars on the twenty dollars register 2O and one ten dollars on the ten dollars register 20. The slides or bars L and a of the hundreds column will register one five dollars on the five dollars register and two dollars on the dollars register. The slides of the tens column will register once each on the fifty cents register, the twenty-live cents register and the five cents register, the ten cent bar or slide e being locked against movement. The slide o of the units column will cause an additional nickel to be registered on the nickel register, while the slide a will be locked against movement so that no pennies will be registered. The $297.85 item is thus analyzed into the different denominations of which it is composed, and the operator knows at a glance what denominations of money and the number of each denomination which must be withdrawn from the bank .in order that this item can be paid. Upon the return movement of the main operating lever 3, the resetting rod or bail 38 engages the hooked ends 30 of those register actuating bars which were previously moved forwardly, with the result that all of the said bars are reset or returned to their original positions. In the meantime the adding machine keys are released in the usual manner so that all of the keys are returned to their normal positions and the detents 31 permitted to engage the shoulders 29 of the register actuating slides. This completes the operation of adding, listing and denominating, the adding and listing being done by the adding machine mechanism in the well known manner. The different items are charged into the machine successively and the cycle of operation for each item is identical with that justdescribed. The registers 2O are preferably in the form of accumulators so that the denominations for each ofthe items which are charged into the machine will be outomatically added to the denominations already registered for the items previously charged into the machine. The attachment is provided with keys corresponding to the special keys ioo 2 ot the adding machine, so that these special keys can be operated with the attachment in position. When it is desired to get the total or subtotal for the items which have been charged into the machine, the proper special key is depressed and the main operating lever 3 actuated in the usual manner. No one of the detents 31 of the attachment will be released, so that there will be no movement oi' any of the register actuating slides and no actuation of any ot the denominator registers. The adding machine, however, will give the total or sub-total, so that the operator will have a list of the items and also the total value of all ot' the diilerent items. rl`his, however, is not suicient to enable the total value of the money to be drawn from the bank in proper denominations to pay or disburse the different items, and Where adenominator device or machine is not available, tedious mental calculations are Jfrequently necessary for ascertaining how the money should be drawn from the bank. rlhese ditlicult calculations are avoided by the use of the denominator attachment which operates automatically tov analyze the items into the different denominations and to register the denominations upon suitable registers. YV hen the operatorgets his total from the adding machine, he has merely to consult the registers on the denominating attachment to know the enact denominations and the exact amount of each denomination in which the money must be drawn from the bank. This is determined with accuracy and precision, so that the possibility of error is avoided as well as the tediousness ot a mental computation. Owing to the facility and ease with which the attachment can be applied to an adding machine or removed therefrom, the adding machine can be used without the attachment for the usual routine work where a denominator is not necessary and would be superfluous. Ordinarily, the denominator attachment would merely be applied to the addingl machine on certain days of the week or month when a payroll or the like is to be made up. The adding machine is thus temporarily enabled to denominate in addition to its usual adding and listing functions, and the expense incident to providing a complete denominating machine in addition to the adding machine is thereby avoided. As previously explained, the denominating machines which are now available are complicated and expensive mechanisms, and since their use is restricted very largely to the making up ot payrolls, they are idle much of the time, and can only be afforded by large concerns having heavy payrolls. An attachment of the present character is thought to supply an existing need for a denominating machine which can be produced at a moderate cost and placed within the reach oi the many concerns which have need for such a device but do not feel justified in purchasing the costly machines heretofore available for that purpose. l/V ith the present attachment the owner uses his adding machine perhaps siX days a week as an adding machine per se and merely places the denominator attachment on the machine on Saturdays or on the lst and 15th days of the month when making up his payroll. Owing to the simplicity of the attachment it can be produced at a very small fraction of the vcost ot the complete denominator machines.
